SELF-DUMPING CAR FOR COKE.

SPECIFICATION forming part of ,Letters Patent No. 630,385, dated August 8, 1899.

Application filed March 17,1899.

To all whom it mag concern:

Be it known that I, J OHN M. MARIS, acitizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Self-Dumping Cars for Coke and other Materials, of which the following is a specification.

My invention relates to improvements in the construction of cars, and more particularly to improvements in automatic or selfdumping cars for hauling coke and other materials.

I-Ieretofore in the construction of cars the longitudinal sills of the car-body spanning or connecting the front and rear bolsters have been stiffened and strengthened to enable them to support the car-body itself and its load without deflection between the bolsters by means of strong truss-rods applied thereto, the truss-rods being supported on suitable struts projecting downwardly from the sill, and as in large long cars designed for carrying heavy loads it is necessary, that the trusses shall extend or project a'con'siderable distance below the sills-in order to be efiective and adequately strengthen and stiffen the sills the car-body itself is necessarily supported a considerable distance above the railway-track by building the trucks high, thus materially diminishing the height and capacity of the car-body w a:, as the total height of the car is limited, and also increasing the liability of the car to leave the track by rendering it top-heavy. The necessity of using strong trusses to stiifen the longitudinal sills of the car-body also of course adds materially to the costof the car.

It is the object of my invention to provide a simple, cheap, efficient, and durable construction of car for hauling coke or other materials by which the'necessity for employing truss -rods applied to and projecting below the longitudinal sills of the car-body may be entirely dispensed with and which will at the 7 same time be much stronger and stifier than the ordinary construction of trussed-car bodies heretofore in use, thus not only saving the expense of the separatetrusses, but also enabling thetrucks to be built as low as desired and the car-bodies supported at as little height above the ground or railway-track as Serial No. 709,499- No model.)

may be required or thought desirable by the user or builder of the car and enabling the car-body box to be made materially lighter and of greater capacity.

My invention consists in the means 1 cmploy to practically accomplish this useful and important object or resultthat is to say, it consists in the combination in a car of the longitudinal sills thereof with an inclined steel-plate bottom therefor connected with the sills, so that the inclined bottom serves not only its ordinary function of automatically dumping or discharging the coke or material in the car but the additional function by reason of its vertical component and its connection with the sills of an effective truss or device for strengthening and stiffening the sills to enable them to support the load. The longitudinal sills and the connected inclined bottom of the car-body thus together form a continuous and unitary structure extending from end to end of the car and triangular in cross-section and which as a whole possesses very great strength and stiffness in resisting the weight of the load or vertical deflection, as the vertical height of the unitary structure from the bottom edges of the longitudinal sills to the peak or ridge of the inclined bottom is very considerable and as the whole body of steel or metal in the inclined bottom is utilized and made effective in giving strength and stiffness to the longitudinal sills or to the structure as a whole.' To adequately connect the steel plates of the inclined bottom with the longitudinal sills of the car and to further strengthen and stifien the structure as a whole, the inclined bottom plates are provided with vertical flanges at their outer edges, overlapping and riveted to the longitudinal side sills of the car-body. The inclined bottom for each side is preferably not formed in one integral plate extending from end to end of the car-body, as that would be an inconvenient length of plate to obtain and handle; but the inclined bottom for each side thereof is preferably or most conveniently formed of a series of steel plates connected at their lower or outer edgesto the longitudinal side sills of thecar-body and connected at the upper edges to a longitudinal ridge-bar at the ridge or peak of the inclined bottom and connected together at their meeting side edges by metal beams, T-irons,

or frame..p'iieces, so as to act as a continuous truss or plate extending from end to end of the car-body, the connecting metal beams, T-irons, or frame-pieces serving also as struts to prevent buckling of the truss-acting inclined bottom plates.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described, and specified in the claims.

I cially designed as one for hauling coke.

In the accompanying drawings, forminga part of this specification, Figure l is a vertical cross-section of a car-body embodying my invention, the car-body shown being spe- Fig. 2 is a partial central longitudinal section taken on line 2 2 of Fig. 1. Fig. 3 is a partial plan view with the bottom plates removed. Fig. 4 is a side elevation ofthe carbody sills and inclined bottom, the inclined bottom plates being in part removed.-

In the drawings similar letters of reference indicate like parts throughout all the figures.

In the drawings A A represent the longitudinal sills of the car-body, the longitudinal side sills A A being preferably steel channelbeams and the central or draw sills A A being preferably steel I-beams. The longitudinal sills A A A A are suitably spaced apart and connected together by transverse connecting-bars a and by the lower'members angle-plates b b and are suitably braced and I by rivetsd, extending through the upright strengthened at the ridge of the inclined bottom by angle-plates b riveted to the vertical flange of the bent T-iron. The triangular frames B are further stiffened by braces b connecting the horizontal member I) and the l inclined members I) b thereof, as will be readily understood from Fig. 1. These braces b, cause the triangular frames to act more efiectively as struts to prevent buckling or deflection of the truss-acting inclined steelplate'bottom D of the car-body under either tension or compression strains.

" is'the ridge-bar, extending longitudinally of the car from end to end at the peak or ridge of the inclined bottom and to which the steel plates composing the inclined bottom are secured at their upper meetingedges flanges d d, formed at the meeting edges of the inclined. bottom plates. The inclined bottom plates D are further each provided with an upright flange or bend d at their outer or bottom edges, fitting fiat against and securely connected with the longitudinal side sills A A of the car-body by rivets 01 thus securely uniting the inclined bottom to the longitudinal sill structure of the car-body, so that the inclined bottom will act and 0perate in unity with the longitudinal sills in giving strength and stiffness to the carbody or structure as a whole. WVhere the inclined bottom plates D for each side of the double inclined bottom are made in separate plates or pieces, as I prefer to construct them and as. illustrated in the drawings, the individual platesor pieces D thereof are preferably connected together, so as to serve as a continuous truss-acting plate from end. to end of the carbody, not by. overlapping the edges of indi vidual plates D and riveting them directly together, but by abutting the meeting edges of the individual plates together and riveting each of the two meeting plates to the connecting and supporting'triangular frame B. This gives a smooth surface to the in.- clined bottom, and the strut-actin g triangular supporting-frames B are thus also located at the joint connecting the individual plates D of the inclined bottom, where they are most needed to prevent buckling of the truss-acting inclinedbottom plates in cases where said bottom plates are made in separate pieces.

F F are the vertical posts for the upper box portion of the car-body frame, the same being preferably composed each of two angle-irons secured together, with a space between, by bolts .or rivets f and spacing-washers f; F, the upper longitudinal sillsfof the car-body frame; F the hinged roof-doors, and F the carlines or transverse beams of the roof-frame. The posts F are furnished withbentor inclined portions f to contract the width of the lower portion of the car-body box to the dis.- t'ance between the longitudinal sills A A. These posts are securely riveted to the longitudinal side sills A A and also to the longitudinal car-box sills F F, which are preferably channel-beams. The posts are connected vto the'roof-plates F F which arepreferably of wood, by bolts f, as indicated in the drawings.

G G are the inclined dumpingdoors or gates of the car, the same fitting between the webs f of the double angle-iron postsF Fand shutting against the fianges f thereof. These doors or gates G are hinged or pivotally con- ;nected to the longitudinal car-box sills F F at their upper edges by pivots orhinges g and iare held closed at their lower'edges by the connecting rod and chain g g, the chain being connected to and winding. around the windglass G, secured to a'wind'ing-shaft G suitably mounted or journaledunder the inclined Zbottom at the apex or ridge thereof in the supporting-frames B B. The winding-shaft G is provided with a pawl and ratchet and operating-lever at its end. At eachend the car-body is provided withan end plate H', preferably of' steel,.the same being securely riveted to the postsF at the end of the carbody and also to the frame B at the end of the car-body.

K is the roof of the car, which may be of any suitable construction, and M are transverse T-iron beams connecting the longitudinal channel-sills F F, andN N are the slats of the car-body box, the same being secured to the posts by bolts or suitable means.

The inclined bottom plate is furnished with slots d through which the connecting rod or link g, leading to the hinged doors or gates, extends.

The ridge-bar C is not necessarily made in one integral piece extending from end'to end of the car, but may be made in two or more pieces, if desired, for convenience in handling, care being taken that the joint between the two separate pieces of the ridge-bar shall not come at the same point as the joint between adjacent bottom plates D D.

P is the bod y-bolster of the car, the same being secured to the car-body on the under side thereof and extending between the side sills A and longitudinal sills A, said car-body bolster having an upper portion P, extending from side sills AA over the draw-sills A A. The two portions of the body-bolsters P and P are directly over each other. It will be understood that the cross-section, Fig. 1,shows only one half the length of the body-bolster, the other half of the body-bolster being removed in order to better show the other parts.

I claim 1. In an automatic or self-dumping carbody, the combination with the body-bolsters and longitudinal sills, of an inclined trussacting continuouscar-body bottom having two oppositely-inclined sides connected rigidly together at their upper meeting edges and rigidly connected at their lower edges with the sills from end to end to strengthen and stiffen the same, substantially as specified.

2; In a car-body, the combination with the body-bolsters and longitudinal sills thereof, of an inclined, continuous truss-acting bottom for the car-body connected with the sills and supported and connected to a series of strut-acting frames of triangular shape secured to the sills, substantially as specified.

3. In a car-body, the combination with the body-bolsters and longitudinal sills, of a series of triangular frames rigidly secured thereto, and a truss-acting inclined bottom for the car-bod y, composed of a series of metal plates secured at their lower edges to the longitudinal side sills of the car-body and secured together at their upper meeting edges at the ridge or peak of the inclined bottom, and secured together at their meeting side edges by said triangular frames to which they are rigidly connected, substantially as specified.

4. In a car-body, the combination with the longitudinal sills, of a series of triangular frames rigidly secured thereto, and a trussacting inclined bottom for the car-body, composed of a series of metal plates secured at their lower edges to the longitudinal side sills of the car-body and secured together at their upper meeting edges at the ridge or peak of the inclined bottom, and secured together at their meeting side edges by said triangular frames to which they are rigidly connected, and a ridge-bar at the upper meeting edges of said inclined bottom plates, substantially as specified.

5. In a car-body, the combination with the body-bolsters and longitudinal sills of a double-inclined truss-acting continuous bottom connected to said sills and extending as a truss from end to end of the car-body, a winding shaft and drums mounted under the ridge or peak of said inclined bottom, and dumping doors or gates hinged at their upper edges to the car-body, and connections from the winding-drums to said doors or gates, substantially as specified.

6. In an automatic or self-dumping carbody, the combination with the longitudinal sills and inclined bottom of the car-body, of a series of posts F F,a series of hinged doors G G fitting between the webs of said posts and shutting against the flanges thereof, a winding shaft and drums, and connections leading from the winding-shaft to said hinged doors or gates, substantially as specified.

7. In a car-body, the combination with the longitudinal sills, of a series of triangular frames rigidly secured thereto, a truss-acting inclined steel-plate bottom for the car-body having flanges at their lower edges riveted t0 the longitudinal side sills of the car-body and provided with flanges at their upper meeting edges, and a ridge-bar fitting between and riveted to said last-mentioned flanges of the bottom plates, substantially as specified.
